Dandruff is a common condition that affects the scalp and results in the shedding of dead skin cells. While the exact causes of dandruff are not completely understood, here are some factors that may contribute to its development:
Malassezia: This is a type of yeast that is found on the scalp of most people. When the yeast overgrows, it can lead to irritation and inflammation of the scalp, which can result in dandruff.
Dry skin: People with dry skin are more prone to developing dandruff because their scalp is more likely to become flaky and itchy.
Seborrheic dermatitis: This is a skin condition that can cause red, itchy, and flaky patches on the scalp, as well as other areas of the body.
Poor hygiene: Infrequent shampooing or not washing your hair thoroughly enough can lead to the buildup of oil and dead skin cells on the scalp, which can contribute to dandruff.
Certain health conditions: Some health conditions, such as psoriasis or eczema, can cause dandruff.
